SHOCK ABSORBER FOB MOTOR CARS AND OTHER SUSPENDED VEHICLES.

Application filed February 2, 1922. Serial No. 533,638.

To all whom may concern:

Be it known that I, ERNEST DERIHON, engineer, a subject .of the King of Belium, residing at 364 Rue St. Laurent, iege, Belgium, have invented certain how and useful Improvements in Shock Absorbers for MotorCars and Other Suspended Vehicles, of which the following is a specification, reference being had therein to the accompanying drawing. My Patents Nos. 1068329 of 1912 1068330; 1183281 of 1912; 1290115 of 1919 and 1290116 of 1919 describe "particularly an arrangement comprising valves carried by two blades or vanes in one piece, which is made movable as compared with a fixed wall in an oil cylinder, in such a way that one or other of these valves opens according to the direction of movement from the intermediate position of the spring. The part of the cylinder comprised between each of the two blades or vanes (placed in the intermediate osition) and the fixed wall is bored to a diameter greater than thatof the circumference described by the outer edge of the blades or vanes, with the object of allowing the blade or vane, which has been brought into that part, to oscillate without any resistance, whilst the other blade or vane, en-

tering at this moment the exactly fitting cy ents make mention, can be dispensed with.

by the use of the following arrangement, which is shown by way of example in the annexed drawing. Figure 1 shows a cross section through A-B in the cylinder of the absorber (Figure 2).

Figure 2 shows a longitudinal section through C-D (Figure 1).

The apparatus is composed of an oil cylinder 1 divided at the middle by a cross partition 2. The blades or vanes 3 and 4:, which are solid with the central hub 5 move in the cylinder 1 from one side to another of the partition 2 round the axle 6.

As in the above patents the cylinder 1 is fixed to the chassis of the vehicle, whilst the blades or and 4 are connected to the 5 axis of the vehicle by means of asuitable lever and joint, which are not shown on the drawings.

The blades or vanes. 3 and 4 are provided with an indentation which produce openings such as those at 7, and which are closed alternately by acentral part 8, fitted with slight friction to the cylindrical part 9 of the central hub 5. This arrangement dispenses with the valves which were formerly fitted to the bottom faces of the blades or vanes 3 and 4,

The removable part 8 oscillates freely on the end of the shaft, which itself is solid with the hub 5, which in turn, is solid with the'blades or vanes 3 and 4.

The oscillation of the part 8 thus produces alternately the openings 7, and replaces with advantage the working of the valves.

In the above example, communication between the two compartments of the cylinder 1 is established by ducts 10 formed in the interior of the cylinder 1 to left and right of the partition.

' It will be readily understood from what is said above that, when the spring of the vehicle is compressed or distended, the blades or vanes 3 and 4 swing round the axle in such a way as to hit alternately on the faces 11 and 12 of the blades or vanes 3 and 4 of the part 5, so as to close or clear the openings such as 7 When the opening 7 of the blade or vane, which travels upwards, is exposed, the blade or vane, which travels downwards, forms the corresponding opening 7 and clears the duct 10, which establishes communication between the two compartments of the cylinder 1. At this moment, no breaking action is set 11 but durin the return movement the opening 7 of the blade or vane, which is going downwards again, closes again and .1

up a constant braking action, whatever may be the amplitude of the displacement of the blades or vanes 3 and 4:.

Having now particulariy described and ascertained the net and what marine the formed I declare that wha A shock absorb. in

is solid with the blades or vanes carries, with ERNEST DERIHON. a slight friction fit, a shutter or member the Witnesses: opposite ends or wings of which come alter- CURTIS T. EVERETT,
